aliases:

- GHSA-mqph-7h49-hqfm
details: Weblate is a web based localization tool. In versions prior to 5.17, the
  translation memory API exposed unintended endpoints, which in turn didn't perform
  proper access control. This issue has been fixed in version 5.17. If developers
  are unable to update immediately, they can disable this feature as the CDN add-on
  is not enabled by default.
